====== Chart Installation ======

OpenCPN does not come with charts, however there are many Chart Sources, and it does come with a [[:opencpn:manual_advanced:charts:sources#gshhg_background_charts|Background Map (GSHHS Low Res)]] installed which shows the Continents. This GSHHG Basemap is always displayed, regardless of chart groups, and it can be improved with a [[:opencpn:manual_advanced:charts:sources#chart_downloader_has_high_res_gshhg|High Resolution GSHHG Background Map]]. For more detail see [[:opencpn:manual_advanced:background_map|]].

Charts are a complex subject due to the many Chart Formats available. OpenCPN can read BSB, S-57 unencrypted and early CM93 charts natively. There are also a number of OpenCPN Chart plugins which enable reading specialized and encrypted chart sets.

Having accurate and current charts is important for safe navigation. The USA provides free NOAA Charts as do many other countries. The built-in **ChartDownloader** Tool will download free (S-57) NOAA ENC digital and RNC raster Charts which OpenCPN can read natively without use of a Plugin.
==== Three excellent ways to install Charts ====

  * [[:opencpn:opencpn_user_manual:charts:chart_downloader_tab|]] Download free S-57 charts near or in your area. Recommended first step for new users, to experiment with Charts and learn the process.

      * NOAA Free S-57 Format ENC & RNC Charts (USA)

      * [[https://opencpn-manuals.github.io/main/o-charts/index.html|O-charts Plugin]] enables OpenCPN to read encrypted S-57 RNC and ENC (actually a OpenCPN SENC file). Note: O-charts_pi takes the place of the oeSENC_pi and oeRNC_pi plugins.
      * Start by installing the [[https://opencpn-manuals.github.io/main/o-charts/index.html|O-charts Plugin]], creating an account on [[https://o-charts.org/?lng=en|O-Charts.org]], purchasing some charts and following the instructions.

==== Where is my Chart Directory? ====

Find the location of your Chart Files.

{{:opencpn:manual_basic:get_started:about.png?300}}

  - In OpenCPN, from Toolbar, pick **About "?"**, then click on the //Config File//  link.
  - The file should open in your text editor.
  - Search for the parameter "**BaseChartDir=**"
  - Make note of the Charts Folder path.
  - The other alternative is to try searching your hard drive for "Chart"

==== Android Chart Location ====

There is one notable detail for recent Android users. With recent Android releases aplications are restricted in where on the storage they can access data and you need to place the charts there using something with elevated privileges, like [[https://play.google.com/store/apps/details?id=com.lonelycatgames.Xplore|X-plore file manager]]\\
For OpenCPN to be able to access the charts, they must be placed either under **/storage/emulated/0/Android/data/org.opencpn.opencpn/files** on the device or under **/storage/XXXX-YYYY/Android/data/org.opencpn.opencpn/files** on the SD card.


==== Getting started using OpenCPN consists of 3 basic steps ====

  - //[[:opencpn:manual_basic:get_started:chart_install|]]// (this page) of Charts to be read by OpenCPN (OpenCPN does not include charts)
  - //[[:opencpn:manual_basic:toolbar:options:charts|]]//Basic Features - Main Source for using charts
  - //[[:opencpn:manual_basic:get_started:gps|]]//to communicate with your computer and OpenCPN (Optional, but very useful)
Completing these 3 steps will get you started and allow you to check out the program.

If you still have questions there is a large supportive OpenCPN community in this [[https://www.cruisersforum.com/forums/f134/|Cruisers Forum]].
